Classic trigger-shape: symmetrical rear dorsal and anal fins – though these are not coloured. Often referred to as the ‘Picasso trigger’ as the markings are a little surreal and look as if painted on. Yellow line from mouth to pectoral fin which looks like a jaw line – but isn’t; has three blue vertical lines from top of head at eyes down to the end of this yellow line. Bottom rear half is black and white striped, top rear half is brown grey.
